CLOSURE FOR Application filed April 17.

My invention relates more particularly to that class of closuresfor-bottles, jars, and other rigid containers in which the bottle neck,for example, is enlarged bya peripher- 1 :11 head or otherwise aroundthe mouth of the bottle, and the cap, for example, that known as theCrown cap, which is provided with a cork or other'lining in its crown toseal the mouth of the bottle, is crimped or com- H pressed toform acontracted rim bound tightly around the neck of the bottle, and} securedagainst displacement thereon by the enlargement around the mouth of thebottle.

The Crown cap has heretofore generally been removed when desired by aspecial tool for the purpose which often distorts the cap in removal, sothat it cannot be used again even for temporarily closing the container,as when only part of the contents is .0 to be used at a timef I Theprimary object of my invention is to provide a neck for bottles, jarsand similar containers so formed that the cap, when crimped orcompressed thereon,-as by means of the ordinary crimping machines incom-- mon use, will be securely held in place against leakage anddisplacement, and yet can be easily removed by hand without the use ofany tool, and after removal can be easily replaced on the neck fortemporarily closing the container when only part of its contents havebeen used. I

- To this and other ends, my invention consists broadly of a container,for example, a

bottle, having a neck formed with periphally and upwardly inclined beadsor-shoulders to engage inward prtgections, or some of the corrugations,if a rown cap, on the inside of the rim thereof and lift the cap off theneck as the cap is turned, and with-upwardly and outwardly inclinedparts, by which the rim of the cap, when crimped or con-, tracted aroundthe neck, islocked in lace, and which, when the cap is turned by and,will. act to expand the rim and ease the lif,t-

in of the cap ofl" the neck. 1

. y invention also consists more specifical- 1y, informing theperipherally and up wardly inclined shoulders on the upper sides ofbeads raised around the neck of the bottle, the underside's of which,when the several beads overlap, serve with the outwardly inclined partsof the neck, to engage the inward cap projections and lock the cap. inplace.

separate application for patent filed by me April 17, 1928, Serial No.270,750.

The present application is specifically for another specific form of mybroad invention described but not claimed in my said other application,and consists in forming the peripherally and upwardly inclinedcap-lifting shoulders on the neck in pairs converging downwardly and theparts of-the neck between the shoulders flarin or inclined upwardly andoutwardly. The downwardly converging shoulders will engage the inwardprojections of the cap, crimped or contracted thereon, when turned ineither direction and lift the cap off the neck, and the upwardly andoutwardly inclined parts of the neck between the shoulders will serve:to lock the cap in place when crimped or In order that this specificform of my in- I vention may be fully understood, I shall first describein detail the mode'in' which I at present prefer tocarry the inventionintopractice, and then particularly point out the invention in theclaims.

Reference is to be had to the accompanying drawings forming part of thisapplication in which like parts are designated by the same numbers inall the figures.

' Figure 1 is a sectional side view of a bottle neck with Crown capembodying my invention.

Figure 2 is a cross-sectional view of the same on the line 22, Figure 1.

Figure 3 is a side view of the said bottle neck.

In the drawings, 5 designatesv the Crown cap here shown to illustrateone use of my invention, 6 the corrugated rim thereof which iscontracted, usually by crimping, around the neck of the bottle, and 7the usual internal corrugations on the inside of the rim.

8 designates the bottle neck, which I form with peripherally andupwardly inclined shoulders 9, arranged in pairs converging downwardlyfrom the mouth 10 of the bottle,

tracted thereon, the cap will be locked securely on the neck, and whenthe cap is turned by hand in either direction, and lifted off the neckby the shoulders 9, the rim of the cap will be evenly and graduallyspread by the upwardly and outwardly inclined parts-11, the removal ofthe cap thus facilitated, and the destructive distortion thereof causedby the ordinary tool, prevented. As a result the cap being flexible, canbe easily slipped over the cap-expanding and securing parts 11 andreplaced temporarily to cover the remaining contents of the bottle whenonly a part thereof has been used.

I prefer to make the depth of the converging cap-lifting shoulders 9greater at the bottom where the initial and greatest resistance toremoval of the cap is met and slightly diminishing to the top to make abetter finish at the mouth of the bottle. I

I also may slightly depress transversely the outer parts 12 of the neckbetween the pairs of shoulders at the bottom, the better to accommodatethe part of the rim contracted against the same.

It is evident that this improved form of container neck may be used withother caps than the Crown cap, which have a rim adapted to be contractedbelow the mouth of the bottle and interior projections on the rim whichwill enter between and engage the downwardly converging shoulders 9.

His also evident that other changes may be made in the practice of myinvention without departing from the boundaries thereof as defined bythe following claims.

I claim as my invention:

1. A bottle or other container having its neckformed with shouldersinclined peripherally and upwardly toward the mouth and arranged inpairs converging downwardly so as to be engaged by intervening inwardprojections on the rim of the cap and lift the cap when turned in eitherdirection, and with parts intervening the shoulders inclined outwardlyand upwardly toward the mouth to engage and lock the caprim contractedaround the. neck and to expand the rim when the cap is lifted by theinclined shoulders.

2. A bottle or other container in accord with claim 1, in which theconverging shoulders decrease in depth toward'the mouth.

In testimony whereof I aflix my signature.

ANTHONY FRANCIS MODONNELL.
